In november i lost my birth control two days into a new pack and had unprotected sex (he didnt cum) the day i lost it. I took plan b less than 24 hrs later and stopped taking birth control completely. It has been 49 days since i had sex and i am a month late for my period. Ive taken 4 tests and they were all negative. Yesterday i took one and another negative, and the past two days i have been having dark brown clots thats now faded to light brown discharge with bad cramps. I have been a bit nauseous with headaches and extremly tired but nothing else. Anyone know whats going on?!?!?!
